The inner core of earth remains a solid ball of metal due to the immense pressure it experiences from the layers above it.

The inner core is made up of mostly iron and nickel and is the hottest part of the Earth, with temperatures reaching up to 5,400°C (9,800°F). However, despite the high temperatures, the inner core remains solid due to the immense pressure from the weight of the outer core, mantle, and crust above it.

This pressure is so great that it prevents the inner core from melting and keeps it in a solid state. Additionally, the inner core is also believed to be slowly growing as the outer core cools and solidifies onto it.

This growth is thought to contribute to the Earth's magnetic field, which is generated by the movement of molten metal in the outer core.

First, we will calculate the number of moles of mixture of Xenon and Neon gases.Number of moles of mixture of Xenon and Neon gases:

Let x be the mole fraction of Neon.

Therefore, (1 - x) is the mole fraction of Xenon

.Mole fraction of Neon + Mole fraction of Xenon = 1x + (1 - x) = 1x = 1 - (1 -

x = 0 + x

x = 0.279

Mole fraction of Neon = 0.279

Mole fraction of Xenon = 0.721

Number of moles of gas = (Total Pressure * Volume)/(Gas Constant * Temperature)

Number of moles of Xenon = (7.10 atm * 16.75L * 0.721)/(0.08206 * (273 + 30))

Number of moles of Xenon = 8.44 moles

Number of moles of Neon = (7.10 atm * 16.75L * 0.279)/(0.08206 * (273 + 30))

Number of moles of Neon = 3.29 moles

Now, we can calculate the partial pressure of Xenon and Neon.

Partial pressure of Xenon:

Partial Pressure of Xenon = Mole fraction of Xenon * Total Pressure

Partial Pressure of Xenon = 0.721 * 7.10 atm

Partial Pressure of Xenon = 5.12 atm

Partial pressure of Neon

Partial Pressure of Neon = Mole fraction of Neon * Total Pressure

Partial Pressure of Neon = 0.279 * 7.10 atm

Partial Pressure of Neon = 1.98 atm

Answer:

High salinity, low temperature.

Explanation:

A lot of salt is left behind. This leads to water with  very high salinity

The salinity of the water increases as more salt is dissolved in it. High temperature, density and salinity produce the most dense water.

Salinity influences the physical properties of water, such as density and heat capacity, together with temperature and pressure.

When two water samples of the same volume are compared, the water sample with the higher salinity will have more mass and be more dense.

The ocean's salinity is raised by both sea ice production and ocean water evaporation. However, processes that reduce salinity, such as the ongoing inflow of fresh water from rivers, precipitation of rain and snow, and melting of ice, constantly balance out these "salinity rising" causes.

Thus, salinity ,density and high temperature produce the water dense.

The refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

To calculate the kilowatt-hours (kWh) of electric energy used by the refrigerator in 30 days, we need to multiply the power rating by the total running time.

Given:

Power rating of the refrigerator = 500 W

Running time per day = 12 hours

Number of days = 30

First, we need to convert the power rating from watts to kilowatts:

Power rating = 500 W / 1000 = 0.5 kW

Next, we calculate the total energy used in kilowatt-hours (kWh) over the 30-day period:

Energy used = Power rating × Running time × Number of days

Energy used = 0.5 kW × 12 hours/day × 30 days

Energy used = 180 kWh

Therefore, the refrigerator would use 180 kilowatt-hours (kWh) of electric energy over the course of 30 days, assuming it runs for 12 hours each day.

According to the question the pH of the solution is 10.17.

pH is a measure of the acidity or alkalinity of a solution. It is measured on a scale of 0 to 14, with 7 being neutral. Solutions with a pH below 7 are considered acidic and solutions with a pH above 7 are considered basic or alkaline. pH is important to biological processes and environmental chemistry because it affects the availability of certain nutrients, the activity of enzymes, and the growth and activity of microorganisms.

The pH of a solution prepared by mixing 50.00 mL of 0.10 M methylamine, CH 3NH 2, with 20.00 mL of 0.10 M methylammonium chloride, CH 3NH 3Cl, can be calculated using the Henderson-Hasselbalch equation:
pH = pKa + log [(Conjugate Acid)/(Base)]
where pKa is the acid dissociation constant of the base and the conjugate acid is the salt of the base.
In this case, Kb = 3.70 x 10⁻⁴ for methylamine and the conjugate acid of CH₃NH₃Cl is CH₃NH₂.
Therefore, the pH of the solution is:
pH = -log[3.70 x 10⁻⁴] + log[(0.10 M CH₃NH₂)/(0.10 M CH₃NH₃Cl)]

= 10.17

Polymerization is the reaction process by which monomers build to form polymers.

Hydrolysis is the process by which the polymers break down into monomers.

The repeating units formed from small molecules known as monomers are bonded together to form a massive single chain-like molecule known as a polymer. Polymerization is the process through which monomers are converted into polymers.

A water molecule is added to the center of a polymer chain during hydrolysis. In order to bond with either end of the newly split polymer, the water divides into an  OH − and an H + group. This rapid splitting of the water will continue until the polymer is broken down into monomers.

Answer:

77.6 g of Fe will be produced

Explanation:

The balanced chemical equation is 2Fe2O3 + 3C → 4Fe + 3CO2. We have 25.0 g of carbon present in the reaction. To calculate the mass of Fe produced, we can use stoichiometry.

First, we need to convert the mass of carbon to moles:

25.0 g C × (1 mol C / 12.01 g C) = 2.08 mol C

Next, we can use the mole ratio between carbon and iron to calculate the moles of iron produced:

2Fe2O3 + 3C → 4Fe + 3CO2

(2 mol Fe / 3 mol C) × (2.08 mol C) = 1.39 mol Fe

Finally, we can convert the moles of iron produced to grams:

1.39 mol Fe × (55.85 g Fe / 1 mol Fe) = 77.6 g Fe

Therefore, 77.6 g of Fe will be produced.
